ATTACHMENT FOR, VISES.

Specification of Letters Patent.

Patented Jan. 19, 1915.

Application filed November 12, 1913. Serial No. 800,525.

To all whom itmay concern:

Be it known that 1, PETER REGCONI, a sub ject of the King of Italy,residing in the city and county of SanFrancisco and State of California,have invented. new and useful Improvements in Attachments for Vises, ofwhich the following is a specification.

This invention relates to a clamp or device attachable to a vise.

The object of the present invention is to provide a clamp or attachmentfor vises whereby pieces being worked upon, as, for instance, parts ofmachinery, etc., andpau ticularly such as crank-shafts of automobiles,may be firmly clamped and leveled and held in a level position withrelation to the vise and'convenient thereto so that the workman ormachinist can fit and try the fittings or associated parts of thestructure which may be mounted in the attachment clamp.

It is another object of the present invention to provide a clamp orsupport for holding work, and which includes means for leveling the workand for permitting of its free angular adjustment in a horizontal plane,and which device is adjustable so that the work may be held sufficientlyabove the work-bench or adjacent surfaces as to enable the freeapplication and operation of elements related to the work in the clamp.

An important object of the invention is to provide a device attachableto bench vises for the steady and level holding and supporting ofcrank-shafts which are being trued or otherwise worked upon and theconnesting-rods and other elements related to the crank-shaft fitted andturned freely about the crank-shaft while it is in the support. Thepurpose of attaching this to the viseis to provide for the convenientarrange ment, location and support of the work or crank-shaft injuxtaposition to the bench vise, so that the parts can be quicklyremoved and fitted in one or the other, thus resulting in the saving ofthe use of two vises for conducting the simple operation of fittingconnecting-rods to crank-shafts, for instance, and also avoiding theunnecessary steps along the bench from one device to the other.

The invention consists in an attachment having a part applicable andattachable to a vise body, and having a body or guide portion upon whichis longitudinally slidable a bed-plate, to whichis pivotally andadjustably related a clamping jaw carrying a removable and adjustablecomplementary clamp plate, and also includes means for leveling theclamp jaw so that the work in hand may be level.

It also comprises details of construction which will be more fullyexplained by reference to the accompanying drawings, in which- Figure 1is a plan view of the device as applied to a standard form of vise. Fig.2

is a side elevation of the same. Fig. 3 is a cross section on line ofFig. 2.

The invention in its present embodiment comprises a rigidly braced headend or body part 2 in the form of an inverted U, the legs of which areof suitable length and provided with flanges or feet 3 enabling its attachment to a suitable support. In the present adaptation the head orbody part 2 is shown as clamped by set-screws lupon the fixed body part5 of a bench vise 6.

Suitably formed with or attached to the front or body part 2 of thedevice are rearwardly extending parallel guides or rails 7 which areprovided at their rear ends with supporting legs 8 for adjustment uponthe supporting surface, as the bench 9. Slidably mounted along the uppersurface of the guides or table part 7 is a bedplate 10 of suitable formand may be of suificient width to slightly overhang the sides of thetable 7, the bed-plate 10 being clamped to the table 7 by suitable hookbolts or clamps 11 extending downwardly and hooking under the bottomsurface of the table 7.

Turnably adjustable in the table 7 is a central spindle or bolt 12, ofsubstantial proportions and suitable length, which may be locked inposition by lock nuts 12. The upper head of the bolt is provided with ayoke or pivot bearing 13, in which is mounted a pivot pin 14 supportinga bossor hinge part 15 which is secured to or formed upon the lowersurface of a work receiving plate or jaw 16. The jaw 16 may be ofrectangular cross section so as to form an upstanding back upon whichwork, for instance a crank-shaft, indicated in dotted lines, may befirmly drawn and clamped by a movable clamp plate 17. Through the clampplate 17 projects the outer end of a screw 18, which screw 18 may bejointed at 19 to the work plate or jaw 16 which may be slotted, as at20, to allow the bolt 18 to be thrown upwardly and outwardly to carrythe clamp plate 17 to the rear of the back plate of the jaw '16.Thebottom of the jaw 16 may be provided with an aperture 21 throughwhich the bolt 18 may be projected when it is desired to draw the clampplate 17 downwardly against work resting upon the work rest or jaw 16.

From the foregoing it will be seen that the present device isparticularly useful in holding work in convenient position to the vise6, so that the workmen can clamp one part of the work in the attachmentbetween the jaws 16 and17 and may use the vise 6 for the support ofpieces which are being fitted upon the work held in the attachment.

It is very importantin truing up and fitting mechanical structures,particularly in the case of fitting bushings, connecting-rods and thelike to crank shafts, that great accuracy is obtained. This isfacilitated when the piece is held in the auxiliary attachment of thevise which can be made perfectly level. For the accomplishment of this Iprovide diametrically opposite, vertically adjustable screws 22 whichmay fit in threaded parts 23 of the work plate or jaw 16, the lower endsof the screws 22 resting upon the bed 10 of the device. In this way thework mounted in the jaws l6 and 17 can be leveled up and as the hearingsor other parts are fitted upon the same the accuracy of the latter canbe nicely determined and corrected.

The screw post or standard 12 turnable in the bed 10 permits thevertical adjustment of the work holding jaws 16-17 to the desiredelevation above the bench 9 or the body of the vise 5 when theattachment is supported entirely thereby, so that pieces being fitted tothe work held in the attachment can be swung freely around the work, asis necessary in fitting parts to crankshafts. The attachment providesfor longitudinal adjustment with relation to the vise 6 by the slidingrelation of the bed 10 along the table 7. Again, the horizontal angularrelation of the work may be varied by horizontally turning the jaws16-17 about the pivot post 12.

Having thus described my invention, what I claim and desire to secure byLetters Patent is- I 1. In a removable attachment for Vises which latterare secured to horizontal suports a air ofs aced horizontal rails aninverted U-shaped head to the top portions of the legs of which one endof the rails are connected, said head being adapted to removablystraddle the fixed part of the vise,

Copies of t is, patent may be obtained for which bears the vise, a bedplate on the rails, and a work holder on the bed plate.

2. In a'vise attachment a horizontal table, a pair of legs at the frontend of the table secured thereto and depending therefrom and adapted tostraddle and be secured to the fixed part of the vise, legs at the rearend of the table depending therefrom for seating engagement on thesupporting memher to which the vise afiixed, and a work holder on thetable.

3. In a vise attachment, a table, means to connect the table to thevise, a bed plate adjustable on the table, a vertically adjustable androtatable post on the bed plate, a jaw pivoted to said post so'as toenable its ends to be vertically oscillated, and means between the awand bed plate to hold the aw rigidly against movement on said pivot ofthe post. 7 j

4. Ina vise attachment, a table, means to connect the table to the vise,a bed plate adjustable on the table, a vertically adjustable androtatable post on the bed plate, a jaw pivoted to said post so as toenable its ends to be vertically oscillated, and a pair of verticalscrews adjustably connected to the jaw and depending therefrom andlocated on opposite sides ofthe post and having their lower ends bearingon the table to hold the jaw rigidly against movement on the pivot andto allow same to be adjusted about said pivot.

5. In a vise attachment, a pair of horizontal spaced angle irons, meansto con nect said angle irons together and to the vise, a bed plateseating' on the horizontal parts of the angle irons, hook-bolts, thehooks of which engage under the free edges of the vertical parts of theangle irons, the

upper ends of the bolts being projected through the bed plate, nuts onthe bolts bearing against the top face of the bed plate, and a workholder on the bed plate.

6. In a vise attachment, atable having a central slotted part, a bedplate on the table slidably connected thereto, a post on the bed platevertically adjustable with relation thereto andhaving its lower endreceived in the table slot, a work clamp pivoted to the upper end of thepost, and a pair of vertically adjustable elements interposed betweenthe bed plate and table for holding the clamp in rigid position on thepost and for enabling the clamp to be secured at varying angles to thebed plate.
